A good sports bra can cut that movement in half — by 53 to 59 percent for As and Ds, respectively — which is key to sparing the support structures in your breast, says Joanna Scurr, PhD, a biomechanist at the University of Portsmouth in the United Kingdom who studies bounce. Band Size — The first step is to measure your band size. A general rule of thumb is to not use a bra for over a year. Here's how to dressing-room test all three.
Band Size — The first step is to measure your band size. Breathe out and snugly wrap your measuring tape around your rib cage, right underneath your bust. This should fall right below the band of the bra you are wearing. To help ensure your measurement is not skewed, make sure that the tape measure is level all around. Round to the nearest even number, and the resulting number is your band size. Bust Size — Step two to find your right bra size is to measure your bust.
Take your measuring tape and wrap it around the fullest part of your bust. Round up to the nearest inch and use this number as your bust size in step three. Calculate — Finally, subtract your band size from your bust size and use the chart below to determine your cup size. The general rule is that one inch represents one cup size. For example, if your measurement results in a size of 30C, your sister sizes are 32B and 34A.
Off the First Hook — When you buy a bra, you should initially be able to wear it comfortably on the loosest hook. This can allow for it to stretch over time. If you have to wear it on the tightest hook right away, your band size may be too large.
Smooth Ride — Your band should lay flat and straight against your back. A band that rides up is another sign of one that is too large. Back Bulge — Inversely, if you notice that your skin is bulging over your band, this is a signal that your band could be too small.
However, it may also indicate that you need a different style bra that has straps that sit closer together in the back. Mind the Gap — Cups that gape can be caused by a number of problems. You may be able to easily solve this by tightening the straps or it could indicate your cup size is too large. However, the issue might be that the shape of the cups is the wrong style for your breast type. Look for cups that are angled or cut small if this is your issue. Say No to Overflow — If you are experiencing spillage on either the side or top of your cups, it is a sign that you need to go up a cup size.
Down to the Wire — A common cause of discomfort is underwire digging in or sitting too high on your breast. Because they cinch in back, the straps anchor the bra closer to the body, providing more support.
Shoulder straps help distribute weight better than T-backs key for bigger cups and are more likely to be adjustable and padded. Tank styles typically cover the back more than clasps, but those with allover stretch lack the rigid front straps, adjustability, and support to anchor large chests.
Clasps let you tighten the band, from which 70 percent of the bra's support comes. This is especially vital for larger breasts, which place more demand on the band.
